in Ortiz-Brunel, Carrillo-Reyes, Sánchez, Ruíz-Sánchez & Rodríguez, 2022. 

Background: The Mammillaria series Stylothelae (Cactaceae) includes 16 taxa distributed mostly among the limits of the Chihuahuan Desert (CD) with the Sierra Madre Oriental and the Transmexican Volcanic Belt (TVB). In Jalisco, four pink flowered species occur at the southwestern end of the CD where it meets the TVB. The boundaries and recognition of three species related with M. fittkaui (M. fittkaui complex) are debatable.

Question: Should the taxa of the Mammillaria fittkaui species complex be considered as species?

Studied species: Four pink flowered Mammillaria series Stylothelae (M. fittkaui species complex) and M. zeilmanniana as comparative species.

Study site: Western Mexico.

Methods: Six morphological characters were sampled in specimens from the type locations of three pink flowered species, one locality of Mammillaria sp., and M. zeilmanniana. We used a permutational multivariate analysis of variance on six characters of each of the groups and a discriminant analysis to evaluate the morphological variation among species and to determine the correct classification of each individual.

Results: The analyses identified four well defined morphological groups with statistical significance within the Mammillaria fittkaui complex. We recognized M. fittkaui, M. limonensis, and M. manana as species and here describe M. arreolae as a new species from Jalisco.

Conclusions: In Cactaceae, morphometry has been useful to establish species boundaries. The Mammillaria fittkaui complex includes four species. Mammillaria arreolae differs from the other species by the shorter tubercles, flowers, and fruits. In addition, it develops more than one hooked central spine per areole.

Mammillaria arreolae P. Carrillo & Ortiz-Brunel, sp. nov. 

Diagnosis. Mammillaria arreolae is similar to M. manana and M. limonensis but it produces shorter tubercles [4-5(-7) mm], 1-4 uncinated central spines, shorter flowers (11-14 mm), and shorter ovoid fruits (4-5 mm). Also, it could be confused with M. fittkaui, from which it differs by the presence of axillary bristles, the noticeable thinner radial spines, and the fruit size and shape (ovoid 4-5 mm long in M. arreolae vs ellipsoidal 5-10 mm long in M. fittkaui).

Etymology. The specific epithet honors Hilda Julieta Arreola Nava. She was a professor at the Universidad de Guadalajara, an outstanding cactologist, and an extraordinary human being. She died in September 26 of 2019.

[Botany • 2022] Ruehssia magalloniae (Apocynaceae: Asclepiadoideae) • A New Species from the Cloud Forest of the Sierra Norte of Oaxaca, Mexico

Ruehssia magalloniae García-Mend., D. Sandoval & L.O. Alvarado,  

in Alvarado-Cárdenas, García-Mendoza & Sandoval-Gutiérrez, 2022.

Background: As part of an expedition to checklist the Flora of Oaxaca, a fieldtrip was carried out in the cloud mountain forest of the ‘Sierra Norte’, during which there was a climbing plant found of the genus Ruehssia that differs of any other species in the genus.

Questions: The morphology of the corolla, the gynostegial corona and the fruit, as well as the geographical distribution are all elements that pro-vide a basis for distinguishing between species of Ruehssia. Here we propose a new species on the grounds of the cohesive concept of species.

Studied species: Ruehssia sp. nov.

Study site and dates: Sierra Norte de Oaxaca, México; 1989-2022.

Methods: An analysis of the morphology and distribution of the populations of the species in question and related taxa was conducted using the collected specimens and herbarium material. In respect to the IUCN criteria, a vulnerability category was established for the species.

Results: The species is similar to Ruehssia rzedowskiana and R. calichicola, but there is a morphological difference regarding the corolla, the gynostegial corona, and its distribution. A morphological description of the new species is provided, in addition to images of the revised taxa, and a map of its geographical distribution and state of conservation. A key to the 18 species of Ruehssia in Oaxaca is also included.

Conclusions: Ruehssia magalloniae is recognised as a new species in science. This discovery increases the number of species of Ruehssia listed in Mexico to 39 with a 58 % of endemism.

Keywords: conservation status, endemism, Flora of Oaxaca, Marsdenia, IUCN

Ruehssia magalloniae García-Mend., D. Sandoval & L.O. Alvarado, sp. nov. 

Diagnosis. Ruehssia magalloniae is morphologically similar in vegetative structure, paniculate inflorescence, and long style head, to the individuals of R. rzedowskiana, but it is distinguished from these by its flowers of 1.0­1.1 cm long (vs. flowers 5.0­6.5 mm long in R. rzedowskiana) with corolla white to pinkish abaxially, whitish to yellow-ish with dense pink dots and lines adaxially (vs. yellow flowers in R. rzedowskiana). The lobes of the gynostegial corona are 3.0-3.2 mm long and its apex of stylar head 4.5 mm long (vs. gynostegial corona lobes 1.5-1.7 mm long and apex of stylar head 2.0-2.5 mm long in R. rzedowskiana).

Se incluye una clave de las 18 especies de Ruehssia presentes en Oaxaca.
Conclusiones: Ruehssia magalloniae se reconoce como una especie nueva para la ciencia. Este descubrimiento incrementa a 39 el número de especies de Ruehssia registradas para México, con un 58 % de endemismo.

[Herpetology • 2023] Molecular Phylogeny reveals Distinct Evolutionary Lineages of the Banded Krait, Bungarus fasciatus (Squamata: Elapidae) in Asia

Bungarus fasciatus sensu stricto from Mizoram, India

in Biakzuala, Lalremsanga, Santra, Dhara, ... et Malhotra, 2023.   

The banded krait, Bungarus fasciatus is a widespread elapid snake, likely to comprise several distinct species in different geographic regions of Asia. Therefore, based on molecular phylogenetics and comparative morphology data, we present an overview of the systematic composition of the species to delimit potential biogeographic boundaries. Our phylogenetic analyses, based on four mitochondrial genes, reveal the existence of at least three evolutionary lineages within B. fasciatus, corresponding to Indo-Myanmar, Sundaic and eastern Asian lineages. We are convinced that there are at least three taxonomic entities within the nomen B. fasciatus and restrict the distribution of B. fasciatus sensu stricto to the Indo-Myanmar region. We also provide additional natural history data of the taxon from eastern India. Finally, we advocate further studies to establish the degree of reproductive isolation among these diverging evolutionary lineages and to reassess the systematic status of this species complex especially the Sundaic and eastern Asian lineages.
Map showing the distribution range of Bungarus fasciatus sensu lato, based on the latest species map provided by the World Health Organization (2022); the coloration corresponds to the three distinct evolutionary lineages recovered in the phylogenetic analyses. The type locality of Bungarus fasciatus sensu stricto is indicated by a black star. Localities of specimens used in the morphological analyses are indicated by black filled diamonds (WB), circles (MZ), and triangles (JV).

[Herpetology • 2022] Nyctibatrachus tunga • A New Cryptic Species of Nyctibatrachus (Anura: Nyctibatrachidae) with Description of its Tadpole from the central Western Ghats, India

 Nyctibatrachus tunga
Kumar, Vishwajith, Anisha, Dayananda, Gururaja & Priti, 2022

We describe a new species of night frog belonging to the genus Nyctibatrachus from the central Western Ghats, India. Nyctibatrachus tunga sp. nov. is distinguished from all congeners by a combination of (1) body size medium (SVL 37.0–40.2 mm ♂, 42.4–47.4 mm ♀), (2) head wider than long (HW 16.0–17.6 mm ♂, 17.4–20.3 mm ♀, HL 11.7–13.6 mm ♂, 13.4–15.5 mm ♀), (3) skin on dorsal and lateral surfaces with glandular folds and throat with dense glandular longitudinal folds, belly white, (4) webbing on toes medium, reaching the third subarticular tubercle on either side of fourth toe (5) presence of nuptial pad and femoral glands in adult males, (6) dorsal body color dark brown, ventrally buff colored except belly, (7) finger disc weakly developed (fd3 0.8±0.1 mm ♂, 1.0±0.1 mm ♀; fw3 0.5±0.1 mm ♂, 0.8±0.1 mm ♀), (8) toe disc moderately developed (td4 1.2±0.2 mm ♂, 1.6±0.1 mm ♀; tw4 0.8±0.1 mm ♂, 0.7±0.0 mm ♀), (9) third finger disc without dorso–terminal groove, fourth toe disc with dorso–terminal groove cover bifurcate distally. Further, molecular phylogeny based on two mitochondrial genes (16S rRNA and ND1), reveals that the new species is sister taxon to N. vrijeuni and N. shiradi. Based on the analysis of 16S rRNA, the new species is genetically divergent by 2.0% and 2.6% from N. vrijeuni and N. shiradi respectively indicating weak but consistent differences to these two species. The bioacoustic analysis also indicated that the new species differed from one of its closest congeners, N. vrijeuni by a higher dominant frequency in advertisement calls. At present, Nyctibatrachus tunga sp. nov. is known from streams within evergreen forests and coffee estates of the upper catchment areas of river Tunga in central Western Ghats.

[Entomology • 2023] Holaptilon yagmur • The Genus Holaptilon Beier, 1964 (Mantodea: Gonypetidae): Discussion on the poorly known Boxer Mantis Genus, with A New Species

Holaptilon yagmur
Yilmaz & Sevgili, 2023

The boxer mantis genus Holaptilon Beier, 1964 (Mantodea: Gonypetidae: Gonypetinae) is known to include two flightless species with a similar body size and morphology. Type species of the genus, H. pusillulum Beier, 1964, is reported from Israel and Jordan. An interesting species of the genus was recently identified from Iran (H. brevipugilis Kolnegari, 2018). In this research, a new species of Holaptilon yagmur Yılmaz & Sevgili sp. n. is described from Turkey. This new species was collected from Karacadağ (Şanlıurfa), a volcanic mountain in the Southeastern Anatolia region. Its typical habitat is steppic stony areas. It indicates that the species may be cryptic or nocturnal since it was collected from under stones and ground traps. This finding indicates that the genus is more widespread than previously known and may have more species yet to be discovered. The existence of the genus Holaptilon was reported for the first time in Turkey. Meanwhile, while reviewing the praying mantis list of Turkey, we determined that the samples collected from Ağrı, which are given in the Mantodea list of Turkey, were misdiagnosed as Armene robusta Mishchenko, 1956 and actually belong to the genus Holaptilon, and that Turkey currently hosts 20 praying mantis species/subspecies.

[Herpetology • 2023] Dipsas aparatiritos • A New Species of Dipsas (Serpentes: Dipsadidae) from central Panama

Dipsas aparatiritos
Ray, Sánchez-Martínez, Batista, Mulcahy, Sheehy, Smith, Pyron & Arteaga, 2023 

A new species of Dipsas Laurenti, 1768, from Central Panama is described based on molecular analyses, hemipenial morphology, and external characters. This is the sixth species of Dipsas to be described for the country; the snake has been suspected to exist since 1977 and has not been thoroughly studied until now. Additionally, morphological comparations including scale counts are done with other species within the genus, and the current geographic distribution of Dipsas temporalis (Werner, 1909), the sister species, is updated. Finally, a key to the species of Dipsas currently known from Middle America is presented.

 Dipsas aparatiritos sp. nov. 
Proposed standard English name: Hidden Snail-eating Snake 
Proposed standard Spanish name: Caracolera Escondida

Diagnosis: Dipsas aparatiritos sp. nov. is placed in the genus Dipsas based on phylogenetic evidence (Fig. 1) and the absence of a labial that is noticeably higher than other labials. The species is diagnosed based on the following combination of characters: (1) 15/15/15 smooth dorsals with enlarged vertebral row (1.5–2.4× as wide as adjacent rows); (2) loreal and a preocular in contact with orbit; (3) 7 supralabials with 4th and 5th contacting orbit, 1st supralabial fused with nasal scale; (4) 8–9 infralabials with 3rd to 6th in contact with chin shields, first pair of infralabials not in contact behind symphysial due to presence of two postmentals; (5) 191–196 ventrals in males, 177–197 in females; (6) 122–136 divided subcaudals in males, 111–126 in females; (7) dorsal and ventral color consisting of 17–20 dark brown to black white-bordered body bands (10–12 dorsal scales long anteriorly to 3–5 dorsal scales long posteriorly) separated from each other by white to pale yellow (anteriorly) to pale brown (posteriorly) interspaces measuring 2–6 dorsal scales long, ventral surfaces white with encroachment from the dorsal dark blotches and with smaller blackish marks in-between the blotches, dorsal aspect of head dark reddish brown with small blotches on the labial and temporal scales as well as a pale nuchal collar, throat white with small dark brown to blackish markings, iris pale brown with minute black speckles; (8) 310–465 mm SVL in males, 169–424 mm females; (9) 122–260 mm TL in males, 65–247 mm in females.

Etymology: The species name is an adjective formed from the Greek word aparatíritos (απαρατήρητος), which means unnoticed. The snake has hidden in plain sight for more than forty years at a very well-studied field site for herpetological research. We suggest the common name “Hidden Snail-eater” (“Caracolera Escondida” in Spanish).

[Botany • 2023] Theriophonum blumei (Araceae) • A New Species from Tamil Nadu, India

 Theriophonum blumei      

in Arulanandam, Soosairaj, Raja & Balaguru, 2023.

Theriophonum blumei sp. nov.a new species is described and illustrated from Tamil Nadu, India based on morphological and leaf epidermal features. Although morphologically T. blumei appears to be similar to T. sivaganganum (Ramam. & Sebastine) Bogner having long acuminate spathe, it is different from T. sivaganganum in various aspects such as ellipsoid seed with ridged surface, spinulose and bifid stigma, filiform neuters and berries with purplish strands. T. blumei has echinate pollen sculpture and T. sivaganganum has verrucate sculpture. Added to that, molecular based (rbcL, matK, trnL-F) phylogenetic analysis also indicate that T. blumei is genetically distinct from T. sivaganganum.

The genus Paris is an important and confusing taxon due to high variation within species, and differences between species are sometimes difficult to delimit. Thus, the status of some taxa has changed over time. To clarify the status of Paris species for plant conservation and effective management of this genus in Thailand, we performed an intensive survey in northern Thailand, studied morphological characteristics, and constructed a molecular phylogenic tree, which we compared to recently published results of this genus. Our results indicate that there are two species in Thailand: P. yunnanensis and a new species, P. siamensis. Detailed descriptions, illustrations, and the phylogenetic position of these two species are provided here.

Distributions of the Two Paris Species in Thailand
The distributions of the plants showed that this genus is specific to high-altitude habitats. The two species in Thailand were separated by lowland areas along the Nan river. Paris siamensis was found only in Luang Prabang Range, while P. yunnanensis was more widespread and found in the Phi Pan Nam Range, the Thong Chai Range, and the Daen Lao Range, which connects to the Shan plateau where the same species is found and is connected to the populations in China.

Tillandsia bernalensis Hern.-Cárdenas, Espejo, López-Ferr. & L. Hern., sp. nov.
The new species is similar to Tillandsia parryi but differs in the width of the leaf blades (6–7 × vs. 3.5–3.7 cm in Tillandsia parryi), in the rachis exposure in mature spikes (not exposed vs. exposed), in the color of the floral bracts (bicolored, vinaceous at the apex, green at the base vs. unicolored, red to orange), in the floral bracts form and keel (obovate to oblong, ecarinate vs. elliptic to narrowly elliptic, carinate at the apex), and in the width of the sepals (1.1–1.3 vs. 0.75–1 cm).

Etymology:— Specific epithet refers to the porphyritic monolith Peña de Bernal, on whose cliffs the new species grows.
